Project wizard responsive design

[AlexZhidkov]

"As a user I want project wizard to be responsive to my screen size so I get best user experience working with it"

Steps to get to the wizard:

1. Sign in into the app with your Google account
2. Navigate to "http://localhost:4200/project/self-sourced" URL
3. Open dev tools (F12)
4. Toggle device toolbar (Ctrl + Shift + M)
   Wizard is always vertical - we want to make it change to horizontal on large screens.
   You can see example in eoi-business.component.html
   For smallScreen it uses mat-vertical-stepper
   And for bigScreen it uses mat-horizontal-stepper
   Implement mat-horizontal-stepper for bigScreen in ProjectWizardComponent
